Answer:

So the answer is just 7

Step-by-step explanation:

Let's do the number first.

21/3 = 7 so the answer will contain a 7.

I wonder what the best way to do e^3 is. Here' one way.

e^3 / e^3 = 1 which is just the answer. but suppose e = 5

Then you have (5*5*5)/(5*5*5) = 125/125

anything divided by itself = 1

so 125/125  = 1

A third way you could do it is like this

e^3/e^3 = e^3 * e- 3

Rule when you move anything (except zero) up from the denominator up to the numerator the power becomes the opposite of what it was.

Rule 1a: when you move anything (except 0) down to the denominator from the numerator the sign becomes the opposite to what it was.

Now you can add the powers

e^(3 - 3) = e^0 = 1

From a standard deck of cards… <br> pulling an ace or a king.
Pani-rosa [81]

Answer:

Probability = 2/13 ≈ 15.4%

Step-by-step explanation:

We are looking for probability of drawing an ace or king from a standard deck of cards.

In a standard deck of cards, there are <em>4 ace and 4 king</em>.

4 + 4 = <u>8</u>, this is the number of possible "correct" cards you can draw, which satisfy the conditions.

Since a standard deck has <em>52 cards</em>, this is the number of cards you can draw, the "possible outcomes".

Probability is the <u>number of "correct" outcomes divided by the total possible outcomes</u>.

The probability is 8 / 52, but we need to <u>reduce the fraction</u>.

Both numerator and denominator are divisible by 4.

8 / 52 = 2 / 13

If you want the probability as a percentage, divide 2 by 13 and multiply by 100.

Probability = 2/13 ≈ 15.4%
